Kitchen Science: Sourdough Starter Day Four


Things should be very exciting now. Start watching your starter throughout the day. What are you noticing? How do things smell? We write down our observations, it is a fun way to keep track of what is happening. You now should be able to tell if your starter is hungry. You will notice the starter expanding and deflating. If you notice your starter in crawling down or deflating this is a good sign you need to feed. At this point you may need to feed every 8-10 hours. Do not worry, your starter will tell you when it’s hungry.
